BINDER-FRAME Specification of Letters Patent.

Patented March 24, 1908.

Application led May 9, 1907. Serial No. 372,654r.4

To all 'whom 'it 'may concern:

Be it known that I, FRANK GRI-linnn, a subject of the Emperor of Germany, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have made and invented certain new and useful Improvements in Binder-Frames, of which the followin@P is a specification.

. i y invention relates to binder frames for loose-leaf ledgers, and its object is to provide a frame of this character which will be simple and inexpensive to make, and so constructed that the loose leaves may be readily inserted therein or removed therefrom.

A further object of my invention is to so construct the back or frame that the largest possible amount of adjustment may be secured between the binding plates or sections, in order that a large number of leaves may be inserted and held or bound between the same.

A further object is to so strengthen the frame as to render it capable of withstanding any and all strains which might be imposed thereon, without bending or twisting, so that the moving parts thereof will at all times work readily and evenly.

With these and other ends in view, my invention consists in certain novel features of construction and ycombinations of parts, as will be hereinafter fully described and pointed out in the claims.

In the accompaying drawings, Figure l is a plan view of my device in its closed position, its open position being indicated by dotted lines. Fig. 2 is a sectional view on the line 2 2 of Fig. l. Fig. 3 is a sectional view on the line 3-3 of Fig. l. Fig. 4 is an end view of the device. Fig. 5 is a plan view of a modified form, the expansion mechanism being omitted. Fig. 6 is a sectional view on the line 6 6 of Fig. 5, and Fig. 7 is a perspective view of the key by means of which the device is opened and closed. Fig. 8 is a perspective view of one of the hinged lugs adapted for use in connection with the sheet metal binder. l

In the drawings, l designates the back and 2, 2, the binding plates or sections which are adapted to be moved transversely of said back. These parts are preferably formed by casting, and may be made of any desired metal, though I prefer to use aluminium on account of the lightness thereof. AThe binding plates are provided with end plates 3, which are adapted to slide inside of the flanges 4, 5, which extend upward from the ends of the back. Each binding plate consists of a base portion 6 rounded or curved and provided with a 'flange 7, between which flanges the leaves of the ledger are adapted to be bound and held. On the curved sections 2 are formed the lugs 8, preferably cast integral therewith. The outer portion of the lugs have openings 25 formed therein, through which the rods 26 are adapted to pass, which rods serve to support the covers of the book in the well known manner, and allow of the removal thereof when it is desired to substitute others. In the lugs 8 are pinned or otherwise secured the rods 9, telescoping in the tubes 32 pinned or otherwise secured in the lugs 8 located opposite the same on the opposing section 2, the lugs in which said rods 9 are secured having an enlarged opening 9fL formed therein for the lreception of the end of its respective tube, so that when the sections are brought together and the frame closed, the several tubes will be allowed to enter said opening and the sections 2 brought more closely together. This construction allows of a much greater travel of the two binding sections, and while compact, renders the same capable of receiving and holding a much larger number of leaves than would be the case were the ends `of the tubes caused to strike or abut against the .flanges 7.

Extending lengthwise of the back, and located centrally thereof, is a rod l0 having opposite ends provided with right and left threads, one end of said rod having its bearing in a flange 4, as shown at Il, the other of the flange 5 provided with the key hole or opening 19. The free end of the rod is formed with a reduced or flattened portion 20, its 4extreme end 2l being round for the purpose hereinafter set forth. At or near its center the rod is provided with the enlarged cylindrical portion l2, which is j ournaled in the bearing 13. Vhile this bearing may be of any desired form, I have shown it as conlsisting of a lower part formed integral with the back, and a cap or cover fitting over the enlarged portion of the rod, and screwed or otherwise fastened to said lower part, as clearly shown in Figs. l and 3.

It will be understood from the above that this construction and arrangement of parts prevents any endwise movement of the rod l0, the ring or enlarged portion l2 also serving as a journal therefor. On the ends of this end extending to or within a short distance rod are threaded the nuts 14, each provided with the lateral extending arms or projections 15, to each of which latter is pivoted one end of a lever or rod 16, the opposite end of said rod being pivoted to a lug 28 formed on the binding plate 2, as illustrated in Fig. 2.

Extending lengthwise of the back are the parallel guide rods 17, the ends of which are somewhat reduced in diameter and extended through and upset upon the flanges 4 and 5. By thus shaping or forming the ends of the rods, shoulders 17a are formed thereon which fit tightly against the inner surfaces of said flanges 4 and 5, and said rods being upset on their outer extreme ends against the outer surfaces of said flanges, hold the latter tightly and firmly in position and render the back extremely strong and stiff.

As illustrated in Fig. 2 of the drawings, these rods ass through the heads of the bolts 18, the ends of said bolts passing throughv the ends of the levers 16 and through the arms or projections 15 formed on the traveling nut 14 and provided on the extreme end of the nuts 18a in order to securely hold the several parts in their proper relative positions. It will be understood that as the rods are rotated in the manner hereinafter described, these nuts will travel towards or away from each other, depending upon the direction or rotation of the rod.

From the foregoing description it will be understood that if the rod 10 is rotated when the device is in its closed position, as shown in Fig. 1, the nuts 14 will travel towards each other, being guided in their travel by means of the bolts 18 sliding on the guide rods 17. As the nuts thus approach one another, the ends of the levers 16 which are pivoted to the binding plates 2, will be forced away from each other, thus causing said plates to separate as indicated in dotted lines in Fig. 1. After the binding plates have been separated a sufficient distance, and the loose leaf or leaves inserted or removed as the case may be, the rod is again rotated in the opposite direction, thus drawing the binding plates together to firmly clamp the leaves in place. The rod is rotated by means of a key shown in Fig. 7. This key has a squared notch 22 formed in its end from the inner end wall of which extends the cylindrical recess 23. When it is desired to rotate the rod, the key 1s inserted through the opening 19 in the end flange 5, the notch 22 and the recess 23 embracing the squared portion 20, and the cylindrical portion 21 of the rod, respectively. y

On the back 1, and running lengthwise thereof, are formed the ribs or flanges 24, for the purpose of adding strength and rigidity thereto, the extreme ends of said rods also 'acting as stops for the traveling nuts 14 when the sections have been separated to the full distance allowed by the levers 16.

In Figs. 5 and 6 1 have shown a slightly modified construction of the frame, which in this instance, is adapted to be made from sheet steel or other suitable metal. While the back and binding plates are much thinner when made of sheet metal than when cast, they have the same general shape and form above described. 1t will be understood that the expansion mechanism which has been omitted from these figures for the sake of clearness, is the same as that already shown and described. In these figures, 27 designates guide plates, which are secured to the end flanges of the back, and are spaced therefrom a sufficient distance to allow the end plates 3 of the binding plates to slide between said guide lates and end flanges.

The lugs 29, whiclli may be fastened to the flanges of the binding plates in any suitable manner, support the rods 35, and also serve to reinforce the tubular members 36. Instead of mounting the supporting rods on these lugs, as is shown in Figs. 1 to 4, inclusive, I mount said rods in the hinges 30, said 'i hinges comprising a circular upper portion, through which `the rods are adapted to pass, and depending arms 38, the lower portions of which are reduced in width thereby forming shoulders 39, as clearly shown in Fig. 8. l

attach these hinges to the binding plates by passing the reduced portions of the arms 38 through slots or openings 31 formed in said platesat suitable points, the length of said slots being equal to the width of said reduced.' portions, and then turning or bending the ends of said arms outwardly against the inner side of said plates, as shown in Fig. 6,

thus preventing outward movement of the hinges, while the shoulders 39, which rest f upon the outer surface of the binding plates,

will prevent inward movement thereof. The

back and the curved flanges of the binding plates may be covered with leather, cloth, or

other suitable material, in order to give a. finished appearance to the ledger.

By reference to Figs. 1 and 4, it will be seen that I have thickened or reinforced the ends of the sections 2, as illustrated at 37, the curvature of the reinforcement conforming to the curvature of the back 1, so that when the frame is in its closed adjustment, as illustrated in Fig. 4, all danger or liability of the ends scratching or marring the desk or other support on which the book is placed, will be avoided.

It will be seen that 1 have provided a binding frame which may be cheaply and easily constructed, and which may be readily opened or closed to permit of the removal or insertion of the leaves.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A binder frame comprising a back, binding plates, guide rods, traveling members engaging with said guide rods, means connecting said members with said binding plates, and means for moving said members and plates, substantially as described.

2. A binder frame comprising a back, binding plates, guide rods, members mounted and sliding upon said guide rods, means connecting said members 'with said binding plates, and means for moving said members and plates, substantially as described.

3. A binder frame comprising a back, binding plates, guide rods extending lengthwise of said back, members mounted and sliding upon said guide rods, means connecting said members with said binding plates, and means for moving said members and plates, substantially as described.

4. A binder frame comprising a back having end flanges extending upwardly therefrom, 4binding plates, guide rods extending between and supported by said end flanges,

members mounted and sliding upon said guide rods, means connecting said members with said binding plates, and means for moving said members and plates, substantially g5 with said back and binder plates for moving 30 the latter, said back being provided with ribs extending lengthwise thereof, the ends of said ribs forming stops for said traveling nuts, substantially as described.

Signed at Jersey City in the county 'of 35 Hudson and State of New Jersey this 4th day of May A. D. 1907.
